A New Internet-Draft is available from the on-line Internet-Drafts
directories. This draft is a work item of the S/MIME Mail Security
Working Group of the IETF.
Title : Signing Certificate Attribute Specification
Author(s) : J. Schaad
Filename : draft-ietf-smime-sigattr-01.txt
Pages : 7
Date : 07-Jul-98
A set of attacks on SignedData objects have been identified relating to the
fact that the certificate to be used when verifying the signature in a
SignerInfo is not cryptographically bound into the signature. This leads to a
set of attacks where the certificate used to verify the signature is altered
leading to possible incorrect results. This document describes these attacks
and provides ways to deal with some of the attacks.

Send a message to: mailserv(_at_)ietf(_dot_)org(_dot_) In the body type:
"FILE /internet-drafts/draft-ietf-smime-sigattr-01.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
